inverse of+cos(3θ)

Solution

inverse

+ cos (3 θ)

Solution

\frac{arccos ( θ )}{3}

Solution steps

Solve for

cos (3 θ), y = + cos (3 θ)

cos (3 θ) = y

cos (a) = b \Rightarrow a = arccos (b)

3 θ = arccos (y)

Solve for

θ, 3 θ = arccos (y)

\frac{arccos ( y )}{3}

Substitute

y = θ

\frac{arccos ( θ )}{3}
